Abstract: ABSTRACT OF THE INVENTION    A blending/loading system wherein an elongated cylinder or fuel rod is positioned on a turntable underneath a series of hoppers  containing  the  particulates  to  be  blended/loaded.          Separate transfer tubes from each hopper are aligned with the cylinder and are subsequently lowered into the cylinder.  Upon lowering, the cylinder is rotated and nozzles at the ends of the transfer tubes are activated to discharge, disperse and mix the stored particulates into the rotating cylinder.  As the cylinder fills up,  the transfer tubes are withdrawn from the rotating cylinder  until  the  desired  amount  of  fill  is  reached.          Afterwards, the nozzles block any additional flow from occurring as they are raised out of the cylinder.

Title: Thread feed system
Inventor: SARFATI ALBERTO G
IPC: B65H51/22
Filed: 1991-07-04
Abstract: ABSTRACT           A feed system for running threads, in particular for delivering them to thread-processing machines, for example for inserting the weft thread into a loom, feeds the thread tangentially to a drum that is connected to a rotary drive.  The thread drawn off the drum by a draw-off force that acts on the other, far side of the drum, the thread only looping around part of the periphery, the drum rotating at a peripheral speed that is greater than the thread draw-off speed.  The thread is movable by a draw-off force tangential to the drum by slippage pull.  Two adjacent and parallel drums have parallel axes and are divided by fixed intermediate walls so that each drum forms a plurality of areas (that lie one behind the other in the axial direction) for the thread to loop around such that the thread moves from an area of one drum to an area of the other drum.  In order to optimize the operation of a feed system of this kind, the present invention proposes that the outer surface of each drum incorporates annular collars oriented radially outwards and aligned with the planes of the intermediate walls.

Abstract: Abstract of the Disclosure A disposable breath alcohol tester is disclosed which includes a transparent housing defining an interior chamber.  A tube extends through the housing chamber so that one end of the tube is open to one side of the chamber while the  second end  of the  tube  is open exteriorly to the opposite side of the chamber.  An inflatable bladder is connected to the second end of the tube.  The tube contains an alcohol reactant substance which changes color whenever the alcohol content of exhaled air passing through the tube exceeds a predetermined amount and at least a portion of both the tube and the housing are transparent so that the alcohol reactant substance can be observed.   In use,  the person under test inflates the bladder by blowing through the tube and thus through the alcohol reactant substance.          The color of the alcohol reactant substance is then observed in order to determine the alcohol content of the exhaled breath.
